Trimble Awarded Contract to Supply High Precision GPS Receivers for Major
U.S. Atmospheric Research Network

Trimble GPS to be Used in SuomiNet to Better Understand Weather, Climate Changes and the Earth


SUNNYVALE, Calif., Aug. 8, 2000 -- Trimble (NASDAQ:TRMB) announced today that it has been awarded a three-year contract to provide Global Positioning System (GPS) receivers for SuomiNet, a university-based, national GPS network that is being developed for atmospheric research and education in the U.S.

The University Corporation for Atmospheric Research (UCAR) awarded the SuomiNet contract with funding from the National Science Foundation and collaborating universities. Under the three-year contract, Trimble will provide an indefinite quantity, expected to be at least 100 systems per year, of the Companys 4700 GPS receivers with a Micro-centeredTM antenna.

"We are pleased to have been awarded the SuomiNet contract," said Bryn Fosburgh, Trimbles director of Land Survey. "I believe the win highlights our leadership position and firm commitment to provide high precision GPS technologies to the scientific and academic research community worldwide."

About SuomiNet

Trimbles GPS receivers will be used in the SuomiNet network to make thousands of accurate measurements of the upper and lower atmosphere per day. The atmosphere induces delays in GPS signals, which can be converted into water vapor and ionospheric measurements. This data, available in real-time on the Internet, will help university researchers and scientists study, model and assimilate information to improve our understanding in a wide range of areas including floods, regional and global climate changes, meteorology, astronomy and earthquakes.

Trimbles 4700 GPS Receiver and Micro-centered Antenna

Trimbles 4700 GPS receiver and Micro-centered antenna are ideal for geodetic and scientific research. The receiver is a high-performance, dual-frequency GPS reference station, capable of making accurate measurements at the millimeter level. It is compact, lightweight, with low-power consumption and able to withstand extreme environmental conditions.

The Trimble 4700 Micro-centered antenna has sub-millimeter phase center repeatability, reduced multipath and superior low elevation satellite tracking when compared with Choke Ring antennas. Low elevation satellite tracking is especially important for atmospheric research.

About UCAR

The University Corporation for Atmospheric Research (UCAR) is a consortium of 63 universities that grant Ph.D.s in the atmospheric and related sciences The consortium also partners with an increasing number of academic and international affiliates and corporations. Based in Boulder, Colorado, UCAR was founded in 1960 to support and extend the capabilities of the university community, to better understand the behavior of the atmosphere and the global environment, and to foster the transfer of knowledge and technology for improving quality of life worldwide.
